Well, it would allow us to see wether fixed stuff actually compiles and runs - that's not nothing. The biggest problem with fixing stuff like armv5, sparc8, whatever is that it requires adding stuff to our inline assembly. It's easy to accidentally make it not compile, but comparatively harder to make the behaviour even worse than before.
